What term expresses the ratio of moles of reactants and products according to the coefficients in the balanced chemical equation
bogdanovich [222]

Answer:

A) mole ratio

Explanation:            

<em>A mole ratio</em>, also known as a mole-to-mole ratio, <em>is ​the ratio between the amounts in moles of one reactant/product to the moles of the other reactant/product. </em>This ratio is determined considering the coefficients in a balanced chemical equation. This ratio is used in chemical problems as a conversion factor between the compounds involved in the reaction.

How many moles of naphthalene are required to react stoichiometrically with 1.24 moles of 2-bromo-2-methylpropane to produce 1.2
slava [35]

1.24 moles of naphthalene are required to react stoichiometrically with 1.24 moles of 2-Bromo-2-methylpropane to produce 1.24 moles of t-butyl naphthalene.

<h3>Define Naphthalene.</h3>

An organic substance having the formula C 10H 8 is naphthalene. It is the most basic polycyclic aromatic hydrocarbon, and it has a distinctive odor that may be detected at concentrations as low as 0.08 ppm by mass. It is a white crystalline solid. Naphthalene is an aromatic hydrocarbon with a fused pair of benzene rings as its main structural component. It is most well-known for being the major component of conventional mothballs.

given that,

the moles of 2-Bromo-2-methylpropane are 1.24

1 mole of naphthalene reacts with 1 mole of 2-Bromo-2-methylpropane

x moles of naphthalene react with 1.24 mole of 2-Bromo-2-methylpropane

x = 1 * 1.24/1

= 1.24 moles of naphthalene

Is rain turning to snow a physical or chemical change?
aleksklad [387]
Hello There!

Physical changes can be reversed whereas chemical changes can not.
Rain turning to snow is a physical change.
The snow could certainly be changed back into rain.
An example of a chemical change is making toast.
Once the toast is made, it is not possible to reverse.

In short, it is a physical change.

Hope This Helps You!
Good Luck :)
